20090320238 | CAM INTERFERENCE ASSEMBLY OF HINGE AND FOLDABLE DEVICE - A cam interference assembly of a hinge includes a cylinder-shaped first element and a cylinder-shaped second element. The first element defines a through hole in a central portion of the first element. A first mating surface of the first element defines a plurality of depressed portions and a plurality of first recessed cavities capable of retaining oil. The second element defines a fixing hole in a central portion of the second element. A second mating surface of the second element defines a plurality of raised portions configured for engaging with the corresponding plurality of depressed portions, and a plurality of second recessed cavities capable of retaining oil. The first element is rotatable relative to the second element. The first mating surface and the second mating surface face each other. | 12-31-2009 |
20090320242 | HINGE - A hinge includes a shaft including a post, a first interfering member, a second interfering member, a bracket, two washers mounted on the post, a resilient assembly located on the post, and a fastener engaging with the post and exerting force against the washers and the resilient assembly. The first interfering member includes a sleeve portion the opposite ends of which define two openings, and a bottom plate covering one of the openings. The bottom plate defines a through hole through which the post extends. A first depressed portion is formed from the inner surface of the bottom plate. The second interfering member defines a through hole fitting about the post. A first raised portion is formed from one side of the second interfering member engaging with the first depressed portion. The bracket includes a flange defining a hole fitting about the post. | 12-31-2009 |
20100024167 | HINGE AND COLLAPSIBLE DEVICE UTILIZING THE SAME - A hinge includes a first element and a second element. The first element includes a shaft sleeve. The shaft sleeve defines a receiving space along an axial direction, and at lest one locating hole communicating with the receiving space in a circumference of the shaft sleeve. The second element includes an elastic shaft rotatable received in the receiving space, and a locating protrusion on a circumference of the shaft engagable in one of the at least one locating hole. A collapsible device utilizing the hinge is disclosed. | 02-04-2010 |
20100037431 | HINGE AND COLLAPSIBLE DEVICE UTILIZING THE SAME - A hinge includes a first element and a second element. The first element includes a shaft sleeve. The shaft sleeve defines a receiving space along an axial direction, and a depressed part at its distal end. The second element includes an elastic shaft rotatably received in the receiving space, and a protruding portion protruding from the shaft being capable of sliding into the depressed part. A collapsible device utilizing the hinge is disclosed. | 02-18-2010 |
20100043176 | HINGE AND COLLAPSIBLE DEVICE UTILIZING THE SAME - A hinge includes a first connecting member, a shaft, a second connecting member, a first fixing member rotatably mounted to the shaft, a ring immovable fixed to the shaft and abutting against the first fixing member, a number of biasing members all rotationally mounted to the shaft, and a fastener. The shaft extends from the first connecting member, with a threaded distal end of the shaft engaging with the fastener. The second connecting member defines a first depressed portion, a through hole transversely passing through the first depressed portion for rotationally fitting about the shaft, and a fixing slot in a first end of the second connecting member. The first fixing member is received in the first depressed portion, and a fixing protrusion extends from the first fixing member for engaging with the fixing slot. | 02-25-2010 |
20100251518 | HINGE - A hinge includes a first connecting member, a second connecting member defining a through hole, a sleeve member fixed to the second connecting member, a shaft movably mounted to the first connecting member, and a fastener. The sleeve member defines a spiral slide groove therein. A clamping protrusion extends from the first connecting member for slidably engaging in the slide groove. The shaft includes a fixing portion rotatably passed through the sleeve member and the through hole. The fastener is fixed to a distal end of the fixing portion. | 10-07-2010 |
20100269298 | COLLAPSIBLE DEVICE - A collapsible device includes a base, a cover, and a hinge. The hinge includes a first connecting member fixed to the base, a second connecting member defining a through hole, a sleeve member fixed to the second connecting member, a shaft movably mounted to the first connecting member, and a fastener. The sleeve member defines a spiral slide groove therein. A clamping protrusion extends from the first connecting member for slidably engaging in the slide groove. The shaft includes a fixing portion rotatably passed through the sleeve member and the through hole. The fastener is fixed to a distal end of the fixing portion. The second connecting member is fixed to the cover. During the rotation of the cover relative to the base via the hinge, the cover is synchronously moved transversely relative to the base along the axial direction of the hinge. | 10-28-2010 |
20110258810 | HINGE - A hinge includes a fixing bracket having a pole, a rotating bracket, a connecting member, a clamping member, and a male element rotatably sleeved on the pole. The hinge further includes a female element non-rotatably mounted to the pole, an elastic assembly rotatably sleeved on the shaft post, and a fastener fixed to a distal end of the pole. The connecting member is fixed to the rotating bracket. The clamping member is fixed to the connecting member, and the male element is fixed to the clamping member. The hinge further includes a first friction washer located between the rotating bracket and the connecting member, a second friction washer located between the connecting member and the clamping member, and a third friction washer located between the clamping member and the male element. | 10-27-2011 |
